Abstract
A method for checking the function of an engine system having an internal combustion engine includes: (a) ascertaining a first charge adaptation value for acting on a manipulated variable for setting an air supply to the internal combustion engine, and ascertaining a first mixture adaptation value for acting on a manipulated variable for setting a fuel supply at a predefined first operating point of the internal combustion engine, in each case with the aid of a predefined adaptation method; and (b) establishing that an error is present in the engine system when at least one of the offset adaptation values is outside a particular predefined adaptation value range.
